"A new analysis of licensing data shows that not only is use of the GPL and other copyleft licenses continuing to decline, but the rate of disuse is actually accelerating." This shouldn't be surprising. The GPL is complex, and I honestly don't blame both individuals and companies opting for simpler, more straightforward licenses like BSD or MIT-like licenses.

The thing about licenses is that people are free to choose which license to use. You don't like the license? Don't use the license or any project that uses it. Simple.

Don't get on BSD's case for having an ideological freedom.

Certainly don't get on GPL's case for not being selfless. GPL is not a charity and was never intended as such. It's a pragmatic license for a pragmatic kind of freedom, acknowledging the fact that people like to be paid for their efforts (mostly in code and testing), and that freedom needs to be self-sustaining.
